Dealer just called and said that Volvo said my car is already on the boat.  Left March 6 due in California (Port Hueneme) on April 1.  Dealer says that cars can only stay in the port for 72 hours (my guess is that they continually need to make more room for more cars) so my car should be here around April 5.  Total shipping time of about 30 days.  Not bad!
